This is a National Stage of International Application No. PCT/KR2022/013146 filed Sep. 1, 2022, claiming priority based on Korean Patent Application No. 10-2021-0133166 filed Oct. 7, 2021.

The present invention relates to a table, more specifically to a table using translucent stone that partially transmits external light.

Recently, there has been an increasing desire to create a more cozy and diverse living space in line with the societal emphasis on Work and Life Balance (WLB). As part of this trend, there is a growing demand to redecorate indoor interiors or change the surrounding environment of tables to experience a new atmosphere.

In this context, various lighting fixtures that can create diverse atmospheres around the table using lighting have been introduced. These lighting fixtures can be divided into stand-type lighting fixtures designed to be installed in a separate space at a certain distance from the table, and table lighting fixtures installed directly on the table top to provide various forms of lighting on the table top.

While these lighting fixtures have the advantage of creating various atmospheres around the table, they also come with several inconveniences.

Firstly, these lighting fixtures have the drawback that they occupy a certain area of the space around the table or a certain portion of the table top, making it difficult for users to efficiently utilize both the table space and the surrounding area.

Moreover, these lighting fixtures are equipped with wired power supply lines that connect to the socket for illuminating the fixture. These power supply lines, aside from being aesthetically unpleasing, pose risks of obstructing user movement and potential hazards if not handled carefully. Additionally, in the case of table lighting fixtures, users must either drag the power supply line along when moving the table or disconnect and reconnect the plug to another socket, limiting mobility and convenience, particularly when no other sockets are available.

The purpose of the present invention is to provide a translucent stone table that not only offers various lighting effects but also enhances space utilization while providing table functionality.

Another object of the present invention is to provide a translucent stone table that eliminates wired power supply lines, allowing easy mobility without spatial constraints.

The resonance chamber () is a space formed inside the housing ().

The sound output holes () penetrate through the outer wall of the housing ().

The bone conduction speaker () is detachably attached to the stone panel (). The bone conduction speaker () is configured to receive acoustic signals, convert them into vibration signals, and transmit the vibration signals to the stone panel ().

The lighting unit () is located inside the case (). The lighting unit () may include an LED module (), a dimming controller (), and a wireless control unit ().

The LED module () projects light (L) toward the stone panel (). The LED module () can be arranged at a distance of 5 mm to 200 mm from the bottom surface () of the stone panel (). The configuration for emitting light from the LED module () may consist of luminescent LED chips () combined with a PCB board (). Additionally, besides the three-module configuration shown in the drawing, the LED module () can also be applied in other forms such as LED strips, LED blocks, surface-emitting LEDs, LED ropes, or LED bars.

The dimming controller () is connected to the LED module () to regulate the light intensity output from the LED module ().

Depending on the design of the case (), the dimming controller () can be placed inside or outside the case ().

The adapter () is configured for recharging the secondary battery (). The adapter () converts power from an external power source into power with a voltage of 5V, 9V, 12V, or 24V and supplies it to the secondary battery ().

Regarding the size of the stone panel (), considering the LED module's current consumption, rated voltage, power consumption, and the battery's charging capacity, a width within 1 m2 is appropriate.

The present invention relates to a translucent stone table () that maximizes portability and convenience, where it is desirable for the LED chips () embedded within the LED module to emit light through a battery for portability. As the number of LED modules required for illumination increases, the number of LED chips () also increases. Consequently, with increased power consumption, when using a stone panel () larger than approximately 1 m2, portability decreases significantly, and the duration to maintain the same level of illumination decreases rapidly due to increased power consumption from the increased number of illumination modules. In other words, when the size of the stone panel () exceeds 1 m2, the installation of more LED modules leads to increased current consumption and power consumption, resulting in faster battery discharge and potential dimming of the LED light.

Therefore, in embodiments of the present invention, when using LED triple modules, it is desirable to use no more than 30 units, taking the aforementioned factors into account.

For example, when using an LED triple module with 0.06 A and an adapter with 2 A,
